Remark 6.5 Let \(\mathcal {R}\)  be a (2-term) homotopy relative Rota-Baxter operator on an associative 2-algebra \(\mathcal {A}\)  with respect to a bimodule \(\mathcal {M}\) . Then the standard skew-symmetrization process yields a relative Rota-Baxter operator (in the sense of [1]}) on the associated Lie 2-algebra with respect to the representation. For more details, we refer to [2]}.
